Specification of Letters Patent.

Application filed. November 8, 1920. Serial No. 422,414.

To all whom it may concem: I

Be it known that I DAVIS MARINSKY, a citizen of the United tates, and residing at New York, in the county of Bronx and State of New York, have invented certain new and useful Improvements in Retainers for the Closure-Caps of Collapsible Tubes, of which the following is a specification, such as will enable those skilled in the art to which it appertains to make and use the same.

Thisinvention relates to the caps or closure devices of collapsible tubes and other receptacles, and the object of the invention is to provide improved means for retaining a.

cap or closure device in connection with a tube or receptacle against accidental displacement, and with this and other objects in view the invention consists in a retainer of the class and for the purpose specified, constructed as hereinafter described and claimed.

The invention is fully disclosed in the following specification, of which the accompanying drawin forms a part, in which the ingv another form of retainer; and,

ig. 5 a view similar to Fig. 4 with parts in a different position.

In the construction shown in Figs. 1 to 3'inclusive, I have indicated at 10 the upper end portion of a collapsible tube which is provided with a conical head 11 having an upwardly directed reduced and externally threaded neck 12 through which the contents of the tube 10 passes when said tube is compressed. In Figs. 1 to 3 inclusive I have shown at 13 a cap or closure device which is threaded to correspond with the threaded neck 12 and is adapted to be mounted thereon as shown in Flg. 1 ofthe drawing, and said cap, in the form of construction shown, is provided in the 'side wall thereof with an outwardly pressed portion 14.

Myinvention consists in providing means neck and will automaticall for retain ing the cap or closure device 13 agalnst displacement from the tube 10 in the operation of discharging a part of the contents therefrom through the neck 12 and in accomplishing this result I mount-on the threadedneck 12 a wire rin 15 which is movable 1n the threads of. said neck, and, in the form of construction shown, said ring is fashloned' from a piece of wire the end portions of which are twisted together as indicated at 16in Fig. 3 of the drawing to form the ring or ring member 15, and the ends of said wire are extended laterally to form opposltely directed spring members 17, which are passed through apertures 18 in the outwardly pressed portion 14 of the cap or closure device 13 inconnecting the ring 15.

with said cap.

In the use of the device shown in Figs. 1 to 3 inclusive and after the ring or ring member 15 has been connected with the capv or closure device, the ring member is first threaded upon the neck 12 into approxiinately the position shown in Fig. 2 of the drawing after which the cap or closure device 13 is placed and threaded upon the neck 12 in which operation the .ring member 15 is movable inwardly or downwardly upon the neck 12 as the cap or closure device 13 moves downwardly thereon, and this operation is continued until the cap or closure device 13 assumes its sealed or closed position, as shown in Fig. 1. When it is desired to discharge a part of the contents of the tube 10, the cap or closure device 13 is threaded outwardly upon the neck 12, in which operation the ring member 15 is correspondingly.

threaded outwardly upon said neck, and and when the ring member assumes the position shown in Fig. 2 of the drawing the cap or closure device 13 will be released from the drop into a position approximately similar to that shown in Fig. 2 of the drawing thus permitting the discharge of the contents of the tube 10. Y

From the foregoing it will be apparent that I provide a very neat and practically invisible retainer for the cap or closure device 13, and one that canbe made at a nominal cost and easily manufactured as well as being strong and durable when in use. i,

In the construction shown in Figs. land 5 I substitute for the loop 19 a finger 22, the end of which is rovided with an 'enlar. ed head 23, and'sai head is preferably sea ed by solder or otherwise as shown at 24, af-

* ter the cap or closure device 13 has been placed in position, thus producing a seal for said cap or closure device, and whenit is desired to discharge the contents of the tube 10.

the seal at 24 is first broken by inserting a knife between the head 23 and the solder or other sealin element 24 to free the finger 22 from the tu e or the head 11 thereof so that the cap or closure device 13 may be rotated on. the neck 12. When the retainer or the ring member 15 thereof assumes a position approximately similar to that shown in Fig. 5 of the drawing the cap or closure device 13 may be moved 'into the position shown in said figure, and be supported by the finger 22. It will be apparentthat the enlarged head 23 on the end of the finger 22- will prevent the detachment of the cap 13 therefrom, it bein understood that the finger 22 passes throug an aperture in the wall of said cap. It will be understood that while I have shown certain methodsof mounting the cap or closure device 13 in connection with the ring member 15, I am not necessarily limited to these details nor am I limited to the construction of the retainer as a whole from a piece of wire bent in the manner shown herein, as said retainer may be made in any desired manner, and various, changes in and modifications of the construction herein shown and described may be made, within the scopeof the appended claims, without departing from the spirit of my invention or sacrificing its advantages.

Having fully described my'invention, what I claim as new and desire to secure by Letters Patent, is

1. The'combination with a receptacle provided with a threaded neck and a cap having an offset apertured portion, said cap beof the cap for movably securing said cap in connection with said member.

2. A cap retainer for a receptacle provided with a threaded neck upon which the cap is adapted to be mounted, said cap being provided with an offset apertured portion, said retainer comprisin a member, and cap engaging means, sai member being movably mounted on said neck and said means being adapted to be located within said cap and to be passed outwardly through the offset apertured portion thereof for movably connecting the same with said retainer.

In testimony that I claim the foregoing as my invention I have signed my name in presence of the subscribing witnesses this 6th day of November 1920.
